System wont ignite. chgd filter & batteries in thermostat


Does the igniter get hot? If it does, then there is a problem with the gas control, that is, the gas won't come on for some reason. Generally, the gas won't come on if the igniter fails (for safety reasons), so are you sure there is gas flowing? You would hear the cycle start, that is the lighter, and even air flow, but if the gas doesn't come on during that time, the system shuts down in a few seconds.

Furnace has begun to fail to cycle on when shuts off but if switches on base of furnace are switched off and back on will cycle on until desired temp. is reached but will not come back on unless switches...


This sounds like it may be a control board issue. If the thermostat has been changed, and the unit operates correctly after it has been reset, then I am thinking the circuit board in the unit is faulty. When the unit stops working, check for a blinking or steady red light on the circuit board. Alot of the time this will be on or blinking and there will be a legend that tells you what each light stands for. This can help you troubleshoot the issue.

We noticed the humidity went down to 30% and I adjusted the rate to increase Now our Aprilaire 400 says to change the filter. I did that, and it still says to change the filter. The furnace runs fine....


If your humidifier is equipped with a Digital Humidifier Control with Water

Panel change indicator, after replacing the Water Panel, turn the control

knob to the "Test/Reset" position until the "Humidifier On" light blinks to

reset its timer. (Blower must be operating and HVAC calling for heat.) Be sure

to turn the control knob back to it's original setting. If the "Humidifier On"

light continues to blink, your humidifier is in Test mode. DO NOT LEAVE THE
CONTROL IN TEST MODE OR HUMIDIFIER WILL NOT OPERATE.

close the by pass air flow valve. shut off the water supply and finally flow the thermostat wire to the transformer or the controller and shut off or disconnect. Unit should be serviced before winter. Cell may need to be replaced
